1. Election Night, and the Most Popular Tweet of All Time

What can you say about the most popular tweet of all time? When President Obama was re-elected shortly before midnight on Nov. 6, Twitter exploded. But only one tweet was the favorite and retweeted more than 800,000 times. After Obama’s victory was projected by the major news networks, his campaign tweeted three times in a row. The first two messages (including one signed “-bo,” which means POTUS tweeted it himself) were retweeted between 180,000 and 250,000 times. Not too shabby, even by Lady Gaga and Justin Bieber standards. But the third tweet, which simply stated “Four more years” and featured an image of Obama hugging the First Lady, made history 22 minutes later. In the days following Obama’s re-election, articles about the tweet were everywhere, which only increased the retweet tally. So the all-time Twitter record remains, for now.
